Abstract

Provided is a firearm filtration device that collects hazardous materials expelled by the discharge of a weapon system such as small arms, heavy weapons, and larger platform indirect and direct systems. Said weapon system may include a barrel that is either rifled or smooth bore on the internal diameter of the barrel. Said barrel terminates at the muzzle which expels a plurality of projectiles in addition to hot exhaust gases which include a wide array of hazardous materials. This device, in its various configuration, attaches or may be integrated into the muzzle end of any weapon system for the primary use of trapping and containing the hazardous components and gases expelled.

Claims (16)

1. A firearm filtration device that attaches to, and collects hazardous materials expelled by discharge of, a firearm, the device comprising:

(a) an inner membrane housing;

(b) at least one core housing, wherein the at least one core housing contains at least one filter, wherein the at least one filter has a member section with a plurality of holes, wherein the plurality of holes has a reducing size in diameter along a length of the housing towards a exit point of the device;

(c) at least one baffle;

(d) a housing having at least one deflector; and

(e) at least one vent, wherein the at least one vent controls an exit direction of discharged gases and byproducts from the firearm.

2. The filtration device of claim 1 , wherein the at least one filter is a standalone filter.

3. The filtration device of claim 1 , wherein the at least one filter is removable.

4. The filtration device of claim 1 , wherein the at least one filter is replaceable.

5. The filtration device of claim 1 , wherein the at least one filter is recyclable.

6. The filtration device of claim 1 , wherein the at least one filter may be refurbished.

7. The filtration device of claim 1 , wherein the at least one filter captures discharged material, gases, nanosized materials, metallics and solvents by at least one single stage filtration member for specific discharged materials.

8. The filtration device of claim 1 , wherein the at least one filter captures discharged material, gases, nanosized materials, metallics and solvents by at least one multi-stage filtration member for different discharged materials.

9. The filtration device of claim 1 , wherein the at least one filter suppresses visible flashes while capturing discharged materials.

10. The filtration device of claim 1 , wherein the core housing reduces deflected pressure waves by venting materials rearward towards the at least one filter to capture the discharged materials.

11. The filtration device of claim 1 , wherein the core housing suppresses impulse noise and overpressure while the at least one filter captures the discharged materials.
